Improvised Star Trek
Improvised Star Trek explores the final frontier of comedy by turning Star Trek into an improv office comedy. Taking suggestions submitted on Twitter and Facebook, the cast (featuring some of Chicago’s top improvisors) creates a fully improvised episode detailing the adventures of the USS Sisyphus, a less enterprising starship. New episodes are posted every other week. To learn more about the show check out our website, facebook page, or twitter!
Improvised Star Trek is fan production. Star Trek is property of CBS/Paramount.

So, no one told you space was going to be this way. Your ships a joke, you're broke, your love-lifes holographic. Seems like you're always stuck at impulse speed, when it hasn't been your stardate, your starweek, your starmonth, or even your staryear.
